41# DESCRIPTION:
42# Verify that device nodes are modified appropriately during zfs command
43# operations on volumes.
44#
45# STRATEGY:
46# For a certain number of iterations, with root setup for each test set:
47#   - Recursively snapshot the root.
48#   - Send|Receive the root to another root.
49#   - Destroy the original and received roots.
50#
51# At each stage, the device nodes are checked to match the expectations.
52#
53# TESTABILITY: explicit
54#
55# TEST_AUTOMATION_LEVEL: automated
56#
57# CODING_STATUS: COMPLETED (2008-03-04)
